Note unusual time

In 1941 the Australian warship HMAS Sydney II was sunk with the loss of all hands by the German raider HSK Kormoran off the coast of Western Australia. When the wreck site was discovered in March 2008, the wreck site was extensively photographed in 2D, but unfortunately a 3D camera was not available. CMST recently gained access to the archive of 1443 still images and has been successful in extracting a selection of true stereoscopic 3D images of the wreck site. The 3D images of the wreck site provide a unique realism to the scenes, which were not able to be seen in 3D when the wreck was originally surveyed. The 3D images have been extracted from the 2D photos archive, using a process sometimes known as “accidental-stereo”. Advanced image warping and rectification algorithms have been used to match selected 2D image pairs and prepare the 3D images. The presentation will discuss the technique used to extract the 3D images and show a selection of 3D images of the wreck site.

After the talk, there will be a 3D showing of a seven minute video, in room SS07 .
